We will represent the amount of money that Molly has with a m. So it tells us the relationship between Kevin's amount and Molly's amount. It is says Kevin has 2.20 less that 4 times Molly's amount so we could represent it by the equation.
So 3/5=8 servings x=10 servings therefor (3/5)/(8)=x/10 so find x multiply both sides by 10 (10(3/5))/8=x (10(3/5))/8=(30/5)/8=(6)/8=6/8=3/4 he needs 3/4 cup of flower
